静电囚禁Rydberg NO分子的慢衰变过程
Slow decay processes of electrostatically trapped Rydberg NO molecules
摘要：
一氧化氮（NO）分子最初以795 m/s的速度在脉冲超声束中传播，被光激发到长寿命的类氢Rydberg-Stark态，减速并静电捕获在低温冷却的芯片传输线Rydberg-Stark减速器中。通过脉冲电场电离检测减速和捕获的分子$in$ $situ$。减速器的操作是通过将实验数据与颗粒轨迹的数值计算结果进行比较来验证的。研究的时间尺度上的捕获分子的衰变高达1毫秒提供了新的见解的寿命，黑体辐射的影响，里德堡态的NO。
英文摘要：
Nitric oxide (NO) molecules initially traveling at 795 m/s in pulsed supersonic beams have been photoexcited to long-lived hydrogenic Rydberg-Stark states, decelerated and electrostatically trapped in a cryogenically cooled, chip-based transmission-line Rydberg-Stark decelerator. The decelerated and trapped molecules were detected $in$ $situ$ by pulsed electric field ionization. The operation of the decelerator was validated by comparison of the experimental data with the results of numerical calculations of particle trajectories. Studies of the decay of the trapped molecules on timescales up to 1 ms provide new insights into the lifetimes of, and effects of blackbody radiation on, Rydberg states of NO.
